Competing Interests

The authors have read the journal's policy and have the following conflicts: The Zamzee intervention system studied in this research was developed by the nonprofit HopeLab Foundation. Nicole Guthrie, Jana Haritatos, Fred Dillon, and Steve Cole are employed by HopeLab Foundation. HopeLab develops behavioral interventions to improve health in young people. The design, conduct, analysis, and reporting of the intervention pilot study represents a scientific collaboration between HopeLab and Drs. Bradlyn, Yen, and Thompson. At the time of this research, Dr. Thompson was an employee of Santech Inc., which also develops behavioral interventions to improve health. Santech has no financial, intellectual property, or other interests in the Zamzee intervention system. This does not alter the authors' adherence to PLOS ONE policies on sharing data and materials.
